The MyBatis SQL mapper framework makes it easier to use a relational database with object-oriented applications. MyBatis couples objects with stored procedures or SQL statements using an XML descriptor or annotations. Simplicity is the biggest advantage of the MyBatis data mapper over object relational mapping tools.

QUESTION

Error required a bean of type 'XXX' that could not be found

Asked 2022-Apr-07 at 10:25

I'm updating a spring boot project by adding a page called news and it has error below.

Field newsService in com.lrs.admin.controller.NewsController required a bean of type 'com.lrs.admin.service.INewsService' that could not be found.

The code is like below: Application.java

@MapperScan("com.lrs.admin.dao")
@ServletComponentScan
@SpringBootApplication
public class Application extends SpringBootServletInitializer implements EmbeddedServletContainerCustomizer{

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

NewController.java

@Controller
@RequestMapping("/news")
public class NewsController extends BaseController {
    private final static String qxurl="news/list";
    
    @Autowired
    private INewsService newsService;

INewsService.java

package com.lrs.admin.service;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Componnt;
import com.lrs.admin.util.ParameterMap;

    @Component
    public interface INewsService {
        public List<ParameterMap> list();
        public Map<String,Object> getNews(ParameterMap pm);
        public Map<String,Object> edit(ParameterMap pm); 
        public Map<String,Object> add(ParameterMap pm,HttpSession session); 
        public Map<String,Object> del(String newsId); 
    }

NewsService.java

public class NewsService implements INewsService {

    @Autowired
    private NewsDao newsDao;
    

NewsDao.java

public interface NewsDao {
    public List<ParameterMap> list();
    public List<ParameterMap> getAllNewsById(ParameterMap pm);
    public ParameterMap getNewsById(ParameterMap pm);
    public void updateNews(ParameterMap pm);
    public void addNews(ParameterMap pm);
    public void delNews(String roleId);
//  public void delUserRole(String roleId);
}

NewsMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lrs.admin.dao.NewsDao">

</mapper>

I just create those files and not implement any method yet.Is this the reason? Any help?Thx.

ANSWER

Answered 2022-Apr-07 at 09:59

you should annotate @Service on the class which implements the interface instead of the interface itself. That is, annotate the NewsService with @Service, and you can remove the @Component tag from INewsService
